Public Member Functions
MAYAFLUX_API void	attach (Layer &layer, uint32_t body_id) const
	Relate a body element to this collapsible and sync its visibility to the current open state.
Kinesis::AABB2D	bounds () const noexcept
	Header strip region, satisfying Kinesis::HasBounds.
Collapsible &	closed_color (glm::vec3 c)
Collapsible &	initially_open (bool v)
Collapsible &	label (std::string text)
	Draw a text label over the header, background included.
Collapsible &	label_color (glm::vec4 c)
	Label text color. Only meaningful when label() is non-empty.
Collapsible &	open_color (glm::vec3 c)
MAYAFLUX_API Collapsible &	place (FormaTarget buf, Surface &surface, LayoutCursor &cursor, float row_h)
	Register the header element using the cursor's column extents.
MAYAFLUX_API Collapsible &	place (FormaTarget buf, Surface &surface, LayoutCursor &cursor, float x_min, float x_max, float row_h)
	Register the header element and wire the toggle callback.

Public Attributes
FormaTarget	buf
	FormaBuffer backing the header geometry. Valid after place().
LayoutCursor	cursor_out
	Cursor positioned below the header, ready for body elements. Valid after place().
Kinesis::AABB2D	header_bounds {}
	NDC region occupied by the header strip. Valid after place().
uint32_t	header_id {}
	Element id of the header strip. Valid after place().
glm::vec3	m_color_closed { 0.25F }
	Background color when closed. Default: glm::vec3(0.25F).
glm::vec3	m_color_open { 0.35F }
	Background color when open. Default: glm::vec3(0.35F).
bool	m_initially_open { true }
	Starting toggle state. Default: true (open).
glm::vec4	m_label_color { 1.F, 1.F, 1.F, 1.F }
	Label text color. Default opaque white.
std::string	m_label_text
	Text label drawn over the header. Empty = color only.
std::shared_ptr< MappedState< bool > >	open
	Open/closed state. Valid after place(). Write to toggle.

Detailed Description

A collapsible header strip.

Before place() is called, the struct carries only configuration. After place(), header_id, open, buf, and cursor_out are populated. This mirrors the Element pattern: configure with setters, register with a single explicit call.

auto col = Collapsible{}
    .initially_open(false)
    .closed_color({ 0.2F, 0.2F, 0.2F })
    .label("Oscillator")
    .place(window, layer, ctx, cursor, x_min, x_max, row_h);
 
col.attach(layer, body_id);
